Neutrophils, eosinophils, and basophils are classified as what type of cells?

Neutrophils, eosinophils, and basophils are classified as granulocytes because they contain visible granules in their cytoplasm when observed under a microscope. These granules are filled with enzymes and proteins that are crucial for the cells' roles in the immune response. Granulocytes are a subtype of white blood cells (leukocytes) and play vital roles in defending the body against infections, particularly by responding to pathogens such as bacteria and parasites.

Understanding the structure and function of these cells further emphasizes their classification as granulocytes. Neutrophils are integral in the first line of defense against bacterial infections, eosinophils are primarily involved in combating multicellular parasites and allergic responses, and basophils release histamine during inflammatory reactions. This classification is key in immunology and pathology for understanding how the body responds to various challenges.
